Development and Validation of an Eating and Food Literacy Behaviors Questionnaire with Young Adult University Students (FS16-05-19)

Abstract Objectives The purpose of this study was to develop and validate a survey instrument capable of measuring eating and food literacy behaviors in young adult university students. Methods This study had a cross-sectional design and used an online survey for data collection. Participants included a convenience sample of free-living young adult university students aged 18 to 30 years attending a large public university in the southeastern United States. Descriptive information including age, gender, and race/ethnicity was collected. Exploratory factor analysis (EFA), Cronbach's alpha coefficients, and confirmatory factor analysis (CFA) were used to develop and validate the instrument. Results Data from 257 students were analyzed in the EFA. Most of the respondents were white (65.8%) and female (65.6%). The mean age of respondents was 20.0 ± 3.4 years. The EFA returned five factors that explained 57.4% of the total variance suggesting acceptable internal structure. Cronbach's alpha values were: 0.89 = health and nutrition, 0.72 = taste, 0.77 = food preparation, 0.64 = planning and decision making, and 0.63 = convenience. Data from 923 students were used in the CFA. Most of the respondents were white (76.4%) and female (50.3%). The mean age of respondents was 20.6 ± 1.8 years. A CFA confirmed that the 5-factor model was an appropriate fit for the data (Chi-squared = 588.05 (142), RMSEA = 0.06, CFI = 0.98, TLI = 0.97, SRMR = 0.05). Conclusions These results suggest that the proposed questionnaire is capable of measuring young adult university students’ eating and food literacy behaviors as they relate to health/nutrition, taste, food preparation, planning and decision making, and convenience. Funding Sources This project was funded in part by Hatch Project #LAB94331.

Attitude Inventory

Abstract Background The Cancer Attitude inventory (CAI) was developed to measure attitudes toward cancer. The aim of the present study was to describe the development of the Persian version of the CAI and to evaluate its psychometric properties in an Iranian sample. Methods The forward–backward method was used to translate the CAI scale from English into Persian. After linguistic validation and a pilot check, a cross-sectional study was performed and psychometric properties of the Iranian version of the questionnaire were assessed. The scale validation was conducted with a convenience sample of 820 laypeople. Construct validity was assessed through both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency was assessed through Cronbach’s alpha analysis and test-retest analysis. Results Five factors were identified in CAI: isolation, helplessness, fear of consequence, belief of control and independence, and fear of death. The results achieved from the CFA displayed that the data fit the model: the relative chi-square (× 2/df) = 2.98 (p < .001), and the root mean square error of approximation (RMSEA) = .07 (90% CI = .06—.07). All comparative indices of the model had scores greater than .80, demonstrating a good fit to the data. Cronbach’s Alpha and the intra-class correlation coefficient (ICC) were .97, which is well above the acceptable threshold. Conclusions The results indicate that the Persian version of the CAI is practical, reliable and valid. Consequently, the instrument could be used in plans to create positive attitudes about cancer control and treatment among Persian people.

To the authors' knowledge, no data on patient safety culture (PSC) have been reported.AimTo assess PSC in the Italian OOH setting.Design & settingNational cross-sectional survey using the Safety Attitudes Questionnaire — Ambulatory Version (SAQ-AV).MethodThe SAQ-AV was translated into Italian and distributed in a convenience sample of OOH doctors in 2015. Answers were collected anonymously by Qualtrics. Stata (version 14) was used to estimate Cronbach’s alpha, perform exploratory and confirmatory factor analysis, correlate items to doctors’ characteristics, and to do item descriptive analysis.ResultsOverall, 692 OOH doctors were contacted, with a 71% response rate. In the exploratory factor analysis (EFA), four factors were identified: Communication and Safety Climate (14 items); Perceptions of Management (eight items); Workload and Clinical Risk (six items); and Burnout Risk (four items).These four factors accounted for 68% of the total variance (Kaiser–Meyer–Olkin [KMO] statistic = 0.843). Cronbach’s alpha ranged from 0.710–0.917. OOH doctors were often dissatisfied with their job; there is insufficient staff to provide optimal care and there is no training or supervision for new personnel and family medicine trainees. Service managers are perceived as distant, with particular issues concerning the communication between managers and OOH doctors. A large proportion of OOH doctors (56.8%) state that they do not receive adequate support.ConclusionThese findings could be useful for informing policies on how to improve PSC in Italian OOH service.

Abstract Background Disability literacy is the ability to perceive definition of disabled person, their characteristics, difficulties in daily life and solution suggestions, their rights and false thoughts and orientations about them. The aim of the study was to develop the Disability Literacy Scale (DLS) to determine the disability literacy of medical school students with a high probability of encountering disabled people. Methods This study was conducted in 1110 medical school students in 2018-2019 academic year. By using literature 97 questions were collected. DLS was created with 22 questions by taking expert opinions. Correct answer was scored as 1, while wrong or ’do not know’ answer as 0. In order to evaluate the reliability of the scale, item total score correlation and internal consistency (Cronbach’s alpha) analyzes and exploratory and confirmatory factor analysis were used for construct validity. Results Of the 51.1% students were female and their age ranged from 17-40, the mean was 21.1±2.2. After the scale development study, the scale consisted of 14 items and 3 sub-dimensions. Scale items explain 43.21% of total variance and factor loadings ranged from 0.37-0.80. The Cronbach’s alpha coefficient was 0.61, 0.64, 0.51 for communication, health problems and social life sub-dimensions, and 0.68 for the whole scale. The fit of scale and the fit index were found to be acceptable after confirmatory factor analysis. In the last form of the scale, the score that can be taken from scale range 0-14. It was accepted that by increasing of the score, disability literacy level was increased. The mean score of students was 9.79±2.57 and the median was 10.0. The scores obtained from DLS were found to be lower in the first 3 grades (p < 0.001), low level mother and father education (p < 0.001/p=0.012) and who have not yet taken lesson about disability (p = 0.021). Conclusions DLS is a valid-reliable tool for assessing disability literacy levels of medical school students. Key messages It is essential to place disability related lessons from the earliest grades of medical school curriculum. In the literature, DLS seems the first scale about disability literacy and needs to be tested in large communities.

ObjectivesTo determine the validity and reliability of the Spiritual Care Competency Scale (SCCS) among nurses in China.DesignMethodological research.MethodsAfter the SCCS was translated into Chinese, the validity and reliability of the Chinese version of the SCCS (C-SCCS) were evaluated using a convenience sample of 800 nurses recruited from different healthcare centres. The construct validity of the C-SCCS was determined by an exploratory factor analysis (EFA) with promax rotation. Pearson’s correlation coefficients of the C-SCCS and the Palliative Care Spiritual Care Competency Scale (PCSCCS-M) were computed to assess the concurrent validity and construct validity of the C-SCCS. To verify the quality of the component structure, we conducted a confirmatory factor analysis (CFA). We tested the internal consistency and stability of the measure using Cronbach’s alpha coefficient and the Guttman split-half coefficient, respectively, and a factorial analysis was performed.ResultsA total of 709 participants completed the questionnaire (response rate: 88.63%), and all completed questionnaires were suitable for analysis. Three factors were abstracted from the EFA and explained 58.19% of the total variance. The Cronbach’s alpha coefficients of the three subscales were .93, .92, and .89, and the Guttman split-half coefficient for the C-SCCS was .84. The CFA indicated a well-fitting model, and the significant correlations between the C-SCCS and the PCSCCS-M (r=0.67, p<0.01) showed adequate concurrent validity. Nurses’ education and income level showed a significant association with the C-SCCS score.ConclusionThe C-SCCS was shown to be a psychometrically sound instrument for evaluating Chinese nurses’ spiritual care competencies.

Patient-centredness in care is a core healthcare value and an effective healthcare delivery design requiring specific nurse competences. The aim of this study was to assess (1) the reliability, validity, and sensitivity of the Finnish version of the Patient-centred Care Competency (PCC) scale and (2) Finnish nurses’ self-assessed level of patient-centred care competency. The PCC was translated to Finnish (PCC-Fin) before data collection and analyses: descriptive statistics; Cronbach’s alpha coefficients; item analysis; exploratory and confirmatory factor analyses; inter-scale correlational analysis; and sensitivity. Cronbach’s alpha coefficients were acceptable, high for the total scale, and satisfactory for the four sub-scales. Item analysis supported the internal homogeneity of the items-to-total and inter-items within the sub-scales. Explorative factor analysis suggested a three-factor solution, but the confirmatory factor analysis confirmed the four-factor structure (Tucker–Lewis index (TLI) 0.92, goodness-of-fit index (GFI) 0.99, root mean square error of approximation (RMSEA) 0.065, standardized root mean square residual (SRMR) 0.045) with 61.2% explained variance. Analysis of the secondary data detected no differences in nurses’ self-evaluations of contextual competence, so the inter-scale correlations were high. The PCC-Fin was found to be a reliable and valid instrument for the measurement of nurses’ patient-centred care competence. Rasch model analysis would provide some further information about the item level functioning within the instrument.

Abstract Background Antiretroviral therapy (ART) has the most effective treatment for people with HIV, but its effectiveness depends on the individual medication adherence. Morisky Medication Adherence Scale (MMAS-8) is one of the most widely used scales to assess patient adherence. Thus, we aimed to validate a Portuguese version of MMAS-8 and determine its psychometric properties in HIV positive patients. Methods A cross-sectional survey was conducted in Centro Hospitalar Universitário São João (Porto, northern Portugal) at the infectious diseases department. After authorization to use the scale - granted by the author - and, a standard forward-backwards procedure to translate MMAS-8 to Portuguese, the questionnaire was applied to 233 patients with HIV doing ART. Reliability was assessed using Cronbach's alpha and test-retest reliability. Three levels of adherence were considered: 0 to < 6 (low), 6 to < 8 (medium), 8 (high). Results In the studied sample, the mean age was 45.03 years (SD = 11.63), 80.3% men, 19.3% women and 1 transgender, and 53.8% had ≤9 years of education. The mean number of prescribed ART per patient was 1.76. The mean score for the medication adherence scale was 7.29 (SD = 6.74). For the reliability analysis, 12 patients were excluded due to missing data (n = 221). Regarding the level of adherence, 22.5% were low adhering, 71.6% medium and 5.9% high. Corrected item-total correlations showed that 1 item does not correlate very well with the overall scale and was dropped. Scale reliability analysis for the remaining 7 items revealed an overall Cronbach's alpha of 0.661. Women had a protective effect on adherence (OR = 0.31;95%CI:0.15-0.66). Number of years doing ART, age of participants, and type of residence didn't show to be correlated with adherence. Conclusions MMAS-8 is a reliable and valid measure to detect patients at risk of non-adherence. A satisfactory Cronbach's alfa (0.661) was obtained. In general, adherence to medication was medium or high. Key messages This scale can be applied nationwide in other different hospitals, as it could serve as a tool for measuring adherence to ART that can allow for better health care to the ones that are low adhering. A Portuguese version of the MMAS-8 was created for measuring adherence to ART that maintained a similar structure to the original MMAS-8 and good psychometric properties.

Distress Scale

Abstract Background Studies of psychological distress in Sierra Leone have typically used measures which were developed for use in other contexts, and which often have not been adapted or validated for use in Sierra Leone. This has resulted in a lack of reliable information about the patterns of psychological distress within the population, which is a barrier to the development of effective and appropriate mental health services. The aim of the study was to develop a locally-appropriate measure of psychological distress for Sierra Leone. Methods The new measure consists of two instruments: the Sierra Leone Psychological Distress Scale (SLPDS) and a gendered measure of ability to carry out daily tasks—a Function scale—as an indication of the severity of distress. A three-phase mixed methods exploratory sequential study was conducted. Phase 1 was item generation and testing, leading to the development of a set of potential items for both instruments. Phase 2 was a small pilot study (N = 202) leading to the selection of the final set of items for both measures. Phase 3 was a validation phase where the SLPDS and the Function scale were administered with a larger sample of 904 respondents. Item analysis was used to assess the internal consistency of the scales, and Exploratory Factor Analysis to explore the properties of the SLPDS. Results Exploratory factor analysis using the principal axis factoring with an oblique rotation identified a three-factor structure for the 18-item SLPDS. Internal consistency for the SLPDS (Cronbach’s alpha = 0.89) and three subscales was good (Cronbach’s alpha > 0.73). The internal reliability of the male and female versions of the Function scale was also found to be acceptable (Cronbach’s alpha = 0.90 for the female scale and 0.79 for the male scale). Conclusions Together the SLPD and Function scales provide a locally-validated tool which will enable government bodies and local and international non-governmental organisations in Sierra Leone to assess mental health and psychosocial needs. This will support both effective service provision and the evaluation of initiatives designed to improve mental health and psychosocial wellbeing.

Abstract Purpose The purpose of the study was to validate the AQoL-8D questionnaire in the adult population of patients referred to an otolaryngology clinic. Methods AQoL-8D was translated into Polish. 463 patients (age18–80 years) with otolaryngological conditions were assessed with the AQoL-8D, SF-6D, and SWLS questionnaires. We investigated the item content-relevance, factor structure by means of Confirmatory Factor Analysis, corrected item-total correlations, Cronbach’s alpha, Pearson correlation of the AQoL-8D scores with results from SF-6D and from the SWLS questionnaires. Finally, ANOVA was used to test the AQoL-8D ability to group the HRQoL of patients in terms of their otolaryngological management type. Results The median score of item content-relevance was 5.0 for all AQoL-8D items. Confirmatory Factor Analysis revealed the following fit indices: Comparative Fit Index = 0.81; Tucker–Lewis Index = 0.80; and Root Mean Square Error of Approximation = 0.07. Cronbach's alpha for AQoL-8D dimensions ranged from 0.48 to 0.79. Mean item-total correlations over all dimensions, super dimensions, and the instrument overall were higher than 0.3. There was a significant Pearson correlation between the results obtained with AQoL-8D and SF-6D (r = 0.68), and with AQoL-8D and SWLS (r = 0.43). A one-way ANOVA showed a significant effect of management type on HRQoL as measured by AQoL-8D [F(4,458) = 6.12, p < 0.001] Conclusion AQoL-8D provides valid and reliable measures of HRQoL in patients undergoing otolaryngological treatment. Because it is a generic questionnaire, it is possible to make general comparisons of otolaryngology outcomes with those from other subspecialties.

Knowledge Scale

Background: The incidence of dementia is increasing dramatically worldwide. It is important to determine knowledge about the dementia for it’s prevention, early diagnosis, treatment, and care. The psychometric properties of the Turkish version of the Dementia Knowledge Assessment Scale (DKAS-T) were evaluated in this study. Methods: The psychometric study was conducted. A total of 1592 participants were recruited between November 2019 and March 2020. The data were collected using a sociodemographic form and DKAS-T. The language and content validity, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA) were used to assess the validity of the scale. The scale’s reliability was obtained using Cronbach’s alpha coefficient, a paired sample t-test, item-total score correlation, and Hotelling’s T-squared test. Results: The mean age of the sample was 29.38 (±11.50) years; 66.8% (n = 1064) were female, and 54.1% (n = 861) reported their income status as income equal to expenditure. The DKAS-T demonstrated content validity and adequate sensitivity (Kendall W = 0.155, p = 0.093). The scale consisted of seventeen items and was unidimensional, which explained 28.705% of the variance. All the factor loadings were found to be >0.30 in factor analysis. In CFA, all of the fit indexes were >0.95 and root mean square error of approximation (RMSEA) was 0.033. A Cronbach’s alpha value of 0.836 was obtained for the entire scale. It was determined that the scale has invariance according to time (t = −1.362, p = 0.181). Homogeneity of the scale was 3.26%, and there was no absence of reaction bias (Hotelling’s T-squared = 2573.681, p < 0.001). Conclusion: The results demonstrated that the instrument is reliable and generates valid data for the Turkish sample. This scale can be used to determine knowledge about dementia and planning educational interventions in the issue.
